TRUSS PAD Application filed August 5, 1931. Serial No. 555,173.

My invention relates to truss pads.

The principal object of my invention is to provide a truss pad having a head which is freely flexible with relation to the pad proper,

5 such head being adapted to engage the rupture or other injury for the purpose of retaining and treating same. V

A further object of my invention is to provide in a pad of the type mentioned, a head 1-9 adapted to form a vacuum or suction over the injured part whereby the head is properly retained against slippage, and a gently massaging and therapeutic action is set up in the parts.

A still further object of my invention is to provide a simple and inexpensive method of constructing a pad of the above type.

Further objects of my invention will appear from the following detailed description thereof. 7

In the drawing:

Figure 1 is a top view of a truss pad constructed in accordance with this invention.

Figure 2 is a back View of said pad.

Figure 3 is a section on line 33 of Figure 1.

Figure 4 is a section on line 4 4 of Figure 2.

In constructing a truss pad in accordance cw with this invention, a base portion 1 is formed on a metal plate 2 of the proper shape, reference being had to the particular type of pad desired. Formed with the base portion 1 upon the plate 2 is a support 3 having a head 3 at. The support 3 is preferably hollow, having thin walls so that the same is given the desired degree of flexibility, the upper portion of the base under the head 4 being reenforced by means of reticulate partitions or walls 5. The head 4, as clearly shown in F igures 3 and 4, is concaved to form a vacuum or suction cup. On the base portion 1 which is constructed of ordinary vulcanized rubber or other similar material, a cushion or pad 6 is formed, the same being preferably constructed of sponge rubber so as to have a comparatively high degree of compressibility and resilience. The cushion or pad 6 is formed around the support 3 of the head 44, leaving an opening or well 7 entirely surrounding the support thus leaving the long resilient support 3 free to move in any direction on the base, and giving the head 4 complete adaptability to the condition to be treated. The sur face of the head 6 is reticulated as shown at 7 in Figure 1 to add to its frictional or non skid properties.

From the foregoing description the nature and use of my new pad will be apparent to those skilled in the art to which the same appertains.

The base portion 1, support 3 and head 4 are molded on the plate 2 of ordinary vulcanizable rubber, and the cushion portion 6 formed on the base portion 1 surrounding the support, of sponge rubber or other material of great resilience. So molded, the pad is vulcanized or otherwise treated. W hen completed, the pad comprises, as will be noted, a head sustained on the base portion by means of a comparatively long and resilient support, such support extending down 7 to the base through a well or channel in the cushion. It will thus be seen that the head so supported has a high degree of flexibility a cushion formed on said base and having a centrally disposed opening, a head constructed of flexible and resilient material, a tube formed integrally with said head and connecting with said base through said opening and arranged to support said head flexibly and resiliently above said cushion, said head having a concave outer surface.

3. A truss pad comprising a base portion, a cushion formed on said base and having a centrally disposed opening, a head, a tube formed integrally with said head and connecting With said base through said opening and arranged to support said head flexibly and resiliently above said cushion, and reenforcing Walls in said tube immediately under said head.

4. A trusspad comprising a base portibn, a cushion formed on said base and having a centrally disposed Opening, a head constructed of flexible and resilient material, a tube formed integrally With said head and connecting with said base through said opening and arranged to support said head flexibly and resiliently above said cushi0n, said head 7 having a concave outer surface, and reenf0rc= lng Walls 1n said tube innnedlately under said head.
